The company offers a broad range of services including photovoltaic system installation, electric vehicle charging stations (Wallbox), industrial electrical installations, and smart home solutions. Positioned as a regional expert with a strong customer focus, SKA Elektrotechnik benefits from positive customer reviews and a professional online presence. The business operates under the parent company SKATechnologie GmbH, indicating a structured corporate backing. Technically, the website is built on the Shopify platform, leveraging modern web technologies and best practices for performance, SEO, and accessibility.

Security measures include HTTPS enforcement and standard security headers, with no detected vulnerabilities or exposed sensitive data. From a security and compliance perspective, the website demonstrates good privacy practices with a comprehensive privacy policy and cookie consent mechanism aligned with GDPR requirements.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

5 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

SKA Elektrotechnik operates as a small-sized service company within the energy and transportation sectors, focusing on electrical installations and smart home technologies. Its market positioning is regional with a strong emphasis on customer satisfaction and quality service delivery. The business model centers on direct service provision to both residential and industrial clients, supported by digital marketing and customer engagement tools. The parent company SKATechnologie GmbH provides corporate structure and potential resource sharing. The company leverages Shopify for e-commerce and digital presence, indicating a modern approach to business operations. Growth indicators include active content marketing via blogs and customer reviews, as well as a clear focus on emerging technologies like photovoltaic and electric vehicle charging infrastructure.

Security posture

The website maintains a good security posture with HTTPS enforced and multiple security headers implemented. There is no evidence of exposed sensitive information or use of vulnerable libraries. Forms are protected with CAPTCHA mechanisms to prevent abuse. Privacy compliance is evident through cookie consent banners and a detailed privacy policy. However, the absence of a dedicated security policy, incident response information, and vulnerability disclosure channels suggests room for maturity improvement. No WAF or blocking mechanisms interfere with site accessibility, indicating stable hosting and infrastructure. Overall, the security measures are appropriate for the business scale but could benefit from enhanced transparency and formalized security governance documentation.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information, including abuse and security email addresses.
  3. Implement and publicize a vulnerability disclosure policy or security.txt file.
  4. Add a terms of service page to clarify user and customer agreements.
  5. Consider appointing and publishing contact details for a Data Protection Officer to enhance GDPR compliance and trust.

Notes

The website is built on Shopify using the Impact theme version 6.5.0, leveraging modern web standards including HTML5, CSS3, and JavaScript modules. It uses JSON-LD structured data for SEO and rich snippets, including breadcrumb and FAQ schema. The site loads resources from Shopify CDN and integrates third-party apps for reviews and chat support. Performance is optimized with preconnects, preloads, and asynchronous script loading. Mobile responsiveness and accessibility features are well implemented. Hosting is stable and secure via Shopify's infrastructure. Technical risks are minimal, with no outdated or vulnerable components detected. Opportunities exist to enhance security transparency and formalize compliance documentation.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
